What skills do you need to become or want to become an electrician?
One of the first skills we learn is electrical safety common sense.
Let's take electric tools for our daily work as an example. Knowing the right way to work can help us get the job done safely and efficiently. An unnecessary security risk. After all, live work is no joke.
It is therefore very important to understand and use power tools correctly. In this edition, Xiaoxi will provide you with a detailed introduction to the entry level manual for common tools used by electricians. Let's get a look.
1. Electrician's knife
An electrician's knife, a tool used to cut and cut electrical equipment.
When using, everyone should pay attention: the blade should be cut outward, and be careful not to hurt your fingers; immediately after use, insert the blade back into the handle to prevent damage to the blade; it must not be used for live work (since the handle of an electrician's knife has no insulation protection) to avoid the hidden danger of electric shock.
A screwdriver is also called a screwdriver and screwdriver and is mainly used to tighten or remove fasteners.
How exactly does it work? The correct way to hold a screwdriver is to hold the screwdriver with your right hand and rest your palm against the screwdriver's handle so that the mouth of the screwdriver aligns vertically with the notch of the screw. When the screw is loosened, you can lightly press the screwdriver handle with the palm of your hand and quickly turn it with your thumb, middle and index fingers.
Nishino tips. During use, make sure that the metal shaft of the screwdriver does not touch the living body, or cover the metal shaft with an insulating plastic tube to avoid electric shock or short circuit.
3. Electric test pen
A test pen is a tool used to determine the presence of power in electrical equipment or lines.

What is the correct grip? Touch your thumb and forefinger to the top metal, touch the control point with your pen tip, and see if the neon tube glows. If it emits light, it is charged, otherwise it is not charged.
Of course, in addition to measuring the power supply with a test pen, we can also identify a live wire. Use the electric pen to touch the three wires to be tested respectively, and the one that can light the electric pen is the live wire.
4. Electric soldering iron
Electric soldering iron, a necessary tool for repair by melting solder tin, is mainly used for soldering contacts between components.
There are no uniform requirements for the grip of an electric soldering iron. The principle is that it is not easy to tire and easy to use. There are basically two types of grip: the handle and the fist. Before use, the oxide layer of a soldering iron tip is usually removed and tinned with flux, so that a thin layer of tin is always left at the front end of the tip to prevent oxidation and reduce power consumption.
A multimeter is an indispensable tool for maintaining electrical measurements. Indispensable when testing electronic circuits, using a multimeter, you can quickly find faults.
Despite the small size of the multimeter, its functions are extremely effective. It can measure resistance, capacitance, diodes, transistors, DC and AC voltage, current, etc., and find out if there is a short circuit in the circuit, open circuit or leak. The specific operation method of the multimeter can be checked online.
Tips: When choosing power tools, it is recommended to look for conventional manufacturers such as Nishino and pay attention to the completeness of the relevant certifications and product information to ensure ease and safety of use. workspace.
